Cannot access to my admin panel anymore due to wrong redirection

Hi,

i hope there’s someone who could help me with this.
I try to be brief:

I have setup 2 wordpress sites, 1 on mydomain.com and one on mydomain.com/it
I was just trying to see if i could temporary redirect traffic from mydomain.com to mydomain.com/it so this is what i did:

– I went to mydomain.com admin panel and under Setting>General i changed the WordPress URL and Site URL from mydomain.com to mydomain.com/it.

Now, if i go to mydomain.com it gets me to mydomain.com/it but the problem is that i cannot access anymore to mydomain.com admin panel to apply any change so it’s like i lost control of my site.

Is there any way to change redirection back accessing via FTP or with something else?

Thanks a lot in advance to will help me!
